An underappreciated source of nonsense in 21st century discourse is people watching YouTube instead of reading things. It doesn't appear this author read anything, preferring to be spooked and misled by a YouTube video.

   trained them to play DOOM - honestly better than I do.

Maybe the author really really sucks at DOOM, but I think this is a false embellishment:

>> While the neurons can play the game better than a randomly firing player, they’re not very good. “Right now, the cells play a lot like a beginner who’s never seen a computer—and in all fairness, they haven’t,” Brett Kagan, chief scientific officer at Cortical Labs, says in the video. “But they show evidence that they can seek out enemies, they can shoot, they can spin. And while they die a lot, they are learning.” [https://www.smithsonianmag.com/smart-news/a-clump-of-human-b... ]

  To play DOOM, the system feeds visual data to the neurons. For the neurons to react, they have to interpret that data in some way.

This is totally false - not even a misleading metaphor, just plain wrong. The neuronal computer doesn't get any visual information:

>> So how does a petri dish of brain cells play Doom when it doesn’t have any eyes? Or fingers? "We take a snapshot of the game with information like the player’s health and the position of enemies, pass it through a neural network, convert it into numbers, and send the data,” explains Cole. “This is called encoding – essentially turning the game state into signals the neurons can understand. The neurons then fire an output – move left, move right, walk forward, shoot or not shoot – which the system decodes and converts back into actions in the game."

I am also concerned about neuronal computing. But it doesn't really help anyone to spread childish ghost stories about it.

I really hate YouTube, by the way. My dad used to read newspapers and had interesting ideas. Now he watches a bunch of YouTube and he's a huge idiot. It's not (directly) because of age: nobody is immune to narcotic slop. I had to delete my account when I realized how much of my life and cognition I was wasting. I wish others would do the same.

I'm scared about biological computing
